摘要： A strain wave drive comprising: an elliptical wave generator shaft (100) rotatable about an axis (X); a flexible tubular flex spline (500) mounted around the wave generator shaft; a ring gear assembly mounted around the flex spline, the ring gear assembly comprising an output ring gear (200) having a circular inner periphery and being sandwiched between two earth ring gears (300, 400) each having a circular inner periphery; wherein the flex spline has a first number of radially outwardly extending teeth around its outer periphery; and wherein each earth ring gear has the first number of radially inwardly extending teeth to engage with the teeth of the flex spline; and wherein the output ring gear has a second number of radially inwardly extending teeth, wherein the second number is greater than the first number, such that as the wave generator shaft rotates, it causes the flex spline to take up the elliptical form of the wave generator shaft and the teeth of the flex spline engage with teeth of the output ring gear at the major diameter of the ellipse, causing the output ring gear to rotate.

摘要： An actuator (12) is disclosed. The actuator (12) comprises an input shaft (18), a wave generator (56), a pair of flex splines (66,68), a pair of earth annuli (14,16), and an output annulus (20). Each of the pair of flex splines (66,68) are earthed to an earth annulus (14,16). The output annulus (20) comprises a circular spline (92). The wave generator (56) is configured to be activated by rotation of the input shaft (18), and the wave generator (56) is configured to elastically deform both of the pair of flex splines (66,68) when the input shaft (18) activates the wave generator (56).
